Pyloric Duplication Cyst

ABSTRACT

Pyloric duplication is a rare anomaly usually manifested as an abdominal mass or gastric outlet obstruction mimicking infantile hypertrophic pyloric stenosis. We experienced a rare case of pyloric duplication without any evidence of a communication to neighboring organs including extrahepatic biliary tree or pancreatic duct in in a newborn male patient. We performed a complete excision of that lesion without bowel resection and encountered an uneventful postoperative recovery.
